flink-metrics-dogstatsd

A metrics reporter implementation for the DogStatsd protocol: https://docs.datadoghq.com/developers/dogstatsd/datagram_shell?tab=metrics

Note any variables in Flink metrics, such as , <job_name>, <tm_id>, <subtask_index>, <task_name>, and <operator_name>, will be sent to Datadog as tags. Tags will look like host:localhost and job_name:myjobname

Build

./gradlew clean build

Parameters:

  • host - the StatsD server host.
  • port - the StatsD server port.
  • tags - (optional) the global tags that will be applied to metrics when sending to Datadog. Tags should be separated by comma only.
